Here’s some pics of a Mesabi shell-and-tube oil cooler heat exchanger we rebuilt. This oil cooler is for a Komatsu WA1200 loader. Each individual tube was removed for ultrasonic cleaning & reconditioning. All the rubber grommet seals were removed from the tube sheets so the shell-and-tube could be thoroughly cleaned inside & out. After final cleaning, prepping & painting all new rubber grommet seals were installed followed by installation of the reconditioned tubes. The cooler was then pressure tested to ensure all the tubes & seals are leak free & then pressure tested again after the bonnets were installed to make sure they are both leak-free as well.
